非饱和水流方程局部迭代法

SECTIONAL ITERATION METHOD SIMULATING UNSATURATED FLOW

本文提出了局部迭代法,对非饱和水流的非线性方程的迭代解法进行了一定的改进。实际计算表明,数值模拟中使用局部迭代法能节省一定的计算时间。

An iteration method is often used in simulating unsaturated water flow .It is the shortcoming that this method takes more computer time . To overcome the shortcoming , a new numerical method of unsaturated flow is presented in this paper .This method is called sectional iteration method .
